As a seasoned design professional I have memorised most of my shapes....triangles, circles... even rectangles, but I need to do some research on this shape, and for the life of me I cannot think "what to google"! "Square with two rounded corners" isn't working!

I didn't expect to like this answer as much as I did after search for a while. I the name "leaf shape" is emergent of folksonomy, rather than coming from a more formal taxonomy — but regardless I think this is the right answer

Thanks @Danielillo I think you've cracked it. You know "leaf" did vaguely occur to me when I was writing the question, but I didn't fully think it through. Sometimes confirmation from a peer is what's needed to firm up a concept. Leaf shape it is.

@mayersdesign Leaf is good in general, but your example is an extreme version that doesn't really look like a leaf at all, so don't feel bad for not making that connection. I might even call yours a "squared leaf shape".

Given a squircle is a square with rounded corners, you could call this a "half-squircle"*.

* Technically the shape you mention does not fit the mathematical definition a squircle, but it's close enough to be called that by most people in the same way that people call things that are approximately circular a circle.

If you'd ask me to draw a 'half-squircle' I would assume one of us is having a stroke. 'Semi-squircle' sounds even weirder, but more accurate in this sense.

I'd like to note that a squircle is not the same as the typical rounded square with quarter circle corners.

Just a side-note. I would imagine that talking about the use of "squircles" during a logo presentation to a board of execs would be met with confusion and laughter. It's very esoteric so I doubt this word would be readily consumed outside of design professionals.
